OK, so I've been moving my data over to the new disk, but I've run into an issue.
I setup a new disk of 25TB partitions and placed them in a pool. I then setup another pool that consist of my old drive and the new drive. The problem is that the old drive is now full, and I don't know how to setup drivepool correctly. I have the "Super" pool setup to duplicate data, so that data would be copied to the new drive, but as I download more things, the old drive eventually filled up.
I've attached some images to help explain my setup and see if anyone can help me out of this.
